EulerOS 2.0 SP13 : busybox (EulerOS-SA-2026-3008)

high Nessus Plugin ID 332960

Synopsis

The remote EulerOS host is missing a security update.

Description

According to the versions of the busybox packages installed, the EulerOS installation on the remote host is affected by the following vulnerabilities :

 BusyBox before commit 42202bf contains a heap buffer overflow vulnerability in the DHCPv6 client (udhcpc6) DNS_SERVERS option handler in networking/udhcp/d6_dhcpc.c that allows network-adjacent attackers to trigger memory corruption by sending a crafted DHCPv6 response with a malformed D6_OPT_DNS_SERVERS option.
 Attackers can exploit incorrect heap buffer allocation calculations in the option_to_env() function to cause denial of service or achieve arbitrary code execution on embedded systems without heap hardening.(CVE-2026-29004)

Tenable has extracted the preceding description block directly from the EulerOS busybox security advisory.

Note that Nessus has not tested for this issue but has instead relied only on the application's self-reported version number.

Solution

Update the affected busybox packages.
